CHARLES HARTLEY MILLER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO EDWARD G.,WEBB, OF SAME PLACE.

PACKIQNG.

SPECIFICATION forming part of Letters Patent No. 664,487, dated December 5,1 Application filed July 27, 1900. Serial No. 24,983. (No specimens.)

To all whom it may concern.-

Be it known that I, CHARLES HARTLEY MIL- LER, a citizen of the United States, and a resident of the city and county of Philadelphia,

in the State of Pennsylvania, have invented reading the detailed portion of my specifica-' tion.

Figure 1 is a cross-section on line :10 a; of Fig. 2, and Fig. 2 is a side elevation of the packing. Fig. 3 is a sectional View of 2. stuffing-box, showing the packing therein. Fig. 4 is a sketch of a modification.

The packing proper, which lies between the two bufier or washer strips 4 4,is made of the inner core 3, which is preferably a piece of soft rubber and is oblong in cross-section, as shown, or of sufliciently yielding material to take that shape when introduced into the stuffing-box, and the textile covering 2 for this core, which may be made of any suitable textile material, but is most suitably formed of washer strips 4 4, which act to separate the the packing intact under the exigencies of the present practice,where the gland is driven down hard and the face of the packing forced hard against the rod, and the great inconvenience and difficulty of introducing them, es-

inserted therein--or of rubber duck or other I material that is pliable, but sufiiciently stifi for the purpose. Around the packing and the washer-strips is the textile material 5, which can be braided around them.

The cover 5 is usually soon worn oif from the rod-face of the packing; but as its main function is to hold the washer-strip in place until it is inserted in the stufling-box this does no harm to the packing.

Fig. 4 is a sketch in which only one washerstrip is shown at the side of the packing. This is not as good a form as that shownin the other figures, because if the packing is not inserted carefully two pieces of packing may get adjacent to each other without the interposition of a washer-strip. These washer or bufier strips, extending, as they do, substantially from the rod-face to the box-face of the packing, will keep the strips of packing separate from each other, so that even if the packinggets worn so that it has to be removed by a hook the packing will come out in strips instead of in small lumps and pieces.

I-Iavingnow fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A packing consisting of the packing proper, having the core formed of a piece of rubber, oblong in cross-section, when in the stuffing-box, covered with textile material, and a washer-strip, made of a flexible but fairly stiff material, placed at the side of said packing proper, and extending in width substantially from the rod-face to the box-face of the packing, and a textile cover inclosing both the packing proper and the washerstrips, substantially as described.

2. A packing consisting of the packing proper and having the core formed of a piece of soft rubber, oblong in cross-section when in the stuffing-box, and covered with textile material, and washer-strips made of a flexible but fairly stiff material, and placed at either side of the packing proper, and extending in width substantially from the rod-face to the boxface of the packing and a textile cover inc-losing beth the packing 'pioper and the Washer-strips, substantially as described. 10

In witness whereof I have hereunto set my hand this 3d day of July 1900.
